"A small set of patches for audit this time; just three in total and
one is a spelling fix.
The two patches with actual content are designed to help prevent new

Pull networking updates from David Miller:
"Highlights:
1) Support more Realtek wireless chips, from Jes Sorenson.
2) New BPF types for per-cpu hash and arrap maps, from Alexei
Starovoitov.
3) Make several TCP sysctls per-namespace, from Nikolay Borisov.
4) Allow the use of SO_REUSEPORT in order to do per-thread processing
of incoming TCP/UDP connections. The muxing can be done using a
BPF program which hashes the incoming packet. From Craig Gallek.
5) Add a multiplexer for TCP streams, to provide a messaged based
interface. BPF programs can be used to determine the message
boundaries. From Tom Herbert.
6) Add 802.1AE MACSEC support, from Sabrina Dubroca.
7) Avoid factorial complexity when taking down an inetdev interface
with lots of configured addresses. We were doing things like
traversing the entire address less for each address removed, and
flushing the entire netfilter conntrack table for every address as
well.
8) Add and use SKB bulk free infrastructure, from Jesper Brouer.
9) Allow offloading u32 classifiers to hardware, and implement for
ixgbe, from John Fastabend.
10) Allow configuring IRQ coalescing parameters on a per-queue basis,
from Kan Liang.
11) Extend ethtool so that larger link mode masks can be supported.
From David Decotigny.
12) Introduce devlink, which can be used to configure port link types
(ethernet vs Infiniband, etc.), port splitting, and switch device
level attributes as a whole. From Jiri Pirko.
13) Hardware offload support for flower classifiers, from Amir Vadai.
14) Add "Local Checksum Offload". Basically, for a tunneled packet
the checksum of the outer header is 'constant' (because with the
checksum field filled into the inner protocol header, the payload
of the outer frame checksums to 'zero'), and we can take advantage
of that in various ways. From Edward Cree"

git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup
Pull cgroup updates from Tejun Heo:
"cgroup changes for v4.6-rc1. No userland visible behavior changes in
this pull request. I'll send out a separate pull request for the
addition of cgroup namespace support.
- The biggest change is the revamping of cgroup core task migration
and controller handling logic. There are quite a few places where
controllers and tasks are manipulated. Previously, many of those
places implemented custom operations for each specific use case
assuming specific starting conditions. While this worked, it makes
the code fragile and difficult to follow.
The bulk of this pull request restructures these operations so that
most related operations are performed through common helpers which
implement recursive (subtrees are always processed consistently)
and idempotent (they make cgroup hierarchy converge to the target
state rather than performing operations assuming specific starting
conditions). This makes the code a lot easier to understand,
verify and extend.
- Implicit controller support is added. This is primarily for using
perf_event on the v2 hierarchy so that perf can match cgroup v2
path without requiring the user to do anything special. The kernel
portion of perf_event changes is acked but userland changes are
still pending review.
- cgroup_no_v1= boot parameter added to ease testing cgroup v2 in
certain environments.
- There is a regression introduced during v4.4 devel cycle where
attempts to migrate zombie tasks can mess up internal object
management. This was fixed earlier this week and included in this
pull request w/ stable cc'd.
- Misc non-critical fixes and improvements"

bond_get_stats() can be called from rtnetlink (with RTNL held)
or from /proc/net/dev seq handler (with RCU held)
The logic added in commit 5f0c5f73e5ef ("bonding: make global bonding
stats more reliable") kind of assumed only one cpu could run there.
If multiple threads are reading /proc/net/dev, stats can be really
messed up after a while.
A second problem is that some fields are 32bit, so we need to properly
handle the wrap around problem.
Given that RTNL is not always held, we need to use
bond_for_each_slave_rcu().

Commit 85743f1eb345 ("net/mlx4_core: Set UAR page size to 4KB regardless
of system page size") introduced dependency where old VF drivers without
this fix fail to load if the PF driver runs with this commit.
To resolve this add a module parameter which disables that functionality
by default. If both the PF and VFs are running with a driver with that
commit the administrator may set the module param to true.
The module parameter is called enable_4k_uar.

Add per-net sysctl tunables to set the size of sndbuf and
rcvbuf on the kernel tcp socket.
The tunables are added at /proc/sys/net/rds/tcp/rds_tcp_sndbuf
and /proc/sys/net/rds/tcp/rds_tcp_rcvbuf.
These values must be set before accept() or connect(),
and there may be an arbitrary number of existing rds-tcp
sockets when the tunable is modified. To make sure that all
connections in the netns pick up the same value for the tunable,
we reset existing rds-tcp connections in the netns, so that
they can reconnect with the new parameters.

MVNETA_BM has a dependency on MVNETA, so we can only select the former
if the latter is enabled. However, the code dependency is the reverse:
The mvneta module can call into the mvneta_bm module, so mvneta cannot
be a built-in if mvneta_bm is a module, or we get a link error:
drivers/net/built-in.o: In function `mvneta_remove':
drivers/net/ethernet/marvell/mvneta.c:4211: undefined reference to `mvneta_bm_pool_destroy'
drivers/net/built-in.o: In function `mvneta_bm_update_mtu':
drivers/net/ethernet/marvell/mvneta.c:1034: undefined reference to `mvneta_bm_bufs_free'
This avoids the problem by further clarifying the dependency so that
MVNETA_BM is a silent Kconfig option that gets turned on by the
new MVNETA_BM_ENABLE option. This way both the core HWBM module and
the MVNETA_BM code are always built-in when needed.

There are two issues with the current code. First one is that we need
to set res->class to 0 in case we use non-default classid matching.
This is important for the case where cls_bpf was initially set up with
an optional binding to a default class with tcf_bind_filter(), where
the underlying qdisc implements bind_tcf() that fills res->class and
tests for it later on when doing the classification. Convention for
these cases is that after tc_classify() was called, such qdiscs (atm,
drr, qfq, cbq, hfsc, htb) first test class, and if 0, then they lookup
based on classid.
Second, there's a bug with da mode, where res->classid is only assigned
a 16 bit minor, but it needs to expand to the full 32 bit major/minor
combination instead, therefore we need to expand with the bound major.
This is fine as classes belonging to a classful qdisc must share the
same major.

====================
ldmvsw: Add ldmvsw driver
This series adds a new Logical Domains vSwitch (ldmvsw) driver.
The ldmvsw driver code will live in the drivers/net/ethernet/sun/
directory and will operate on Oracle systems running SPARC Linux in a
Logical Domains environment (typically in the control domain).
The ldmvsw driver is very similar in function to the existing sunvnet
driver. Ldmvsw creates a network interface for each "vsw-port" node
found in the Machine Description (MD) of a service domain. These
nodes correspond to ports on a vswitch created by the logical domains
manager. The created network interface(s) can be used by bridge/vswitch
software (such as the Linux bridge or Open vSwitch) to provide
guest domain(s) with network interconnectivity or connectivity
to a physical network.
Here is a example diagram of ldmvsw driver usage in a logical
domain environment to provide a guest domain with network connectivity
to a physical NIC on the service domain:
+----------------+ +-----------------
| Service Domain | | Guest domain |
| | | |
| LinuxBridge | | |
| | | | | |
| NIC Ldmvsw | | Sunvnet |
+----------------+ +----------------+
| | LDC |
LAN ------------------------------
As stated, the sunvnet and ldmvsw drivers are _very_ similar in function.
They both create network interface(s) to receive/transmit network
traffic across LDC network channel(s). Since the driver is so similar
in function to sunvnet, the approach will be as follows to integrate
the driver and take advantage of common code:
Patch #1: Split sunvnet.c driver into sunvnet.c and sunvnet_common.c
Patch #2: Modify the sunvnet_common code and data structures to be compatible
with both the sunvnet and ldmvsw drivers.
Patch #3: Add the new ldmvsw.c driver code
Patch #4: Checkpatch cleanup of the sunvnet/sunvnet_common code.
NOTE - Patch#1 renames a file (sunvnet.h -> sunvnet_common.h). When generating
the patches (using git format-patch), I had to use the --no-renames option
otherwise patch#1 would NOT apply using 'patch -p1' - which as I
understand is a requirement for patch acceptance. I wasn't sure if this
is proper thing to do. Please advise if not. Thanks.
v2 changes:
* change all EXPORT_SYMBOL declarations to EXPORT_SYMBOL_GPL
* remove inline attribute for external function port_is_up_common()
* Give all exported/global funcs in sunvnet_common.c a 'sunvnet_' prefix
to avoid kernel global namespace pollution/collisions
* ldmvsw.c: Order local variable declarations from longest to shortest line
* ldmvsw.c: register the netdevice after all supporting state is ready/setup.
NOTE: The consensus at Oracle is that the following functions
must be done AFTER register_netdev() - this is the same
ordering currently used in the sunvnet driver:
1. sunvnet_port_add_txq_common() - needs registered netdev
2. napi_enable() - requires registered netdev
3. vio_port_up() - as soon as this function is called
LDC handshake messages will come in
which must be handled by the napi code.

Add ldmvsw.c driver
Details:
The ldmvsw driver very closely follows the sunvnet.c code and makes
use of the sunvnet_common.c code for core functionality.
A significant difference between sunvnet and ldmvsw driver is
sunvnet creates a network interface for each vnet-port *parent*
node in the MD while the ldmvsw driver creates a network interface
for every vsw-port node in the Machine Description (MD).
Therefore the netdev_priv() for sunvnet is a vnet structure while
the netdev_priv() for ldmvsw is a vnet_port structure.
Vnet_port structures allocated by ldmvsw have the vsw bit set.
When finding the net_device associated with a port, the common code keys
off this bit to use either the net_device found in the vnet_port or the
net_device in the vnet structure (see the VNET_PORT_TO_NET_DEVICE() macro in
sunvnet_common.h). This scheme allows the common code to work with
both drivers with minimal changes.
Similar to Xen, network interfaces created by the ldmvsw driver will always
have a HW Addr (i.e. mac address) of FE:FF:FF:FF:FF:FF and each will be
assigned the devname "vif<cfg_handle>.<port_id>" - where <cfg_handle> and
<port_id> are a unique handle/port pair assigned to the associated
vsw-port node in the MD.

Modify sunvnet common code and data structures to be compatible
with both sunvnet and ldmvsw drivers.
Details:
Sunvnet operates on "vnet-port" nodes which appear in the Machine
Description (MD) in a guest domain. Ldmvsw operates on "vsw-port"
nodes which appear in the MD of a service domain.
A difference between the sunvnet driver and the ldmvsw driver is
the sunvnet driver creates a network interface (i.e. a struct net_device)
for every vnet-port *parent* "network" node. Several vnet-ports may appear
under this common parent network node - each corresponding to a common parent
network interface. Conversely, since bridge/vswitch software will need
to interface with every vsw-port in a system, the ldmvsw driver creates
a network interface (i.e. a struct net_device) for every vsw-port - not
every parent node as with sunvnet. This difference required some special
handling in the common code as explained below.
There are 2 key data structures used by the sunvnet and ldmvsw drivers
(which are now found in sunvnet_common.h):
1. struct vnet_port
This structure represents a vnet-port node in sunvnet and a vsw-port
in the ldmvsw driver.
2. struct vnet
This structure represents a parent "network" node in sunvnet and a parent
"virtual-network-switch" node in ldmvsw.
Since the sunvnet driver allocates a net_device for every parent "network"
node, a net_device member appears in the struct vnet. Since the ldmvsw
driver allocates a net_device for every port, a net_device member was
added to the vnet_port. The common code distinguishes which structure
net_device member to use by checking a 'vsw' bit that was added to the
vnet_port structure. See the VNET_PORT_TO_NET_DEVICE() marco in
sunvnet_common.h.
The netdev_priv() in sunvnet is allocated as a vnet. The netdev_priv()
in ldmvsw is a vnet_port. Therefore, any place in the common code
where a netdev_priv() call was made, a wrapper function was implemented
in each driver to first get the vnet and/or vnet_port (in a driver
specific way) and pass them as newly added parameters to the common
functions (see wrapper funcs: vnet_set_rx_mode() and vnet_poll_controller()).
Since these wrapper functions call __tx_port_find(), __tx_port_find() was
moved from the common code back into sunvnet.c. Note - ldmvsw.c does not
require this function.
These changes also required that port_is_up() be made
into a common function and thus it was given a _common suffix and
exported like the other common functions.
A wrapper function was also added for vnet_start_xmit_common() to pass a
driver-specific function arg to return the port associated with a given
struct sk_buff and struct net_device. This was required because
vnet_start_xmit_common() grabs a lock prior to getting the associated
port. Using a function pointer arg allowed the code to work unchanged
without risking changes to the non-trivial locking logic in
vnet_start_xmit_common().

Split sunvnet.c into sunvnet.c and sunvnet_common.c.
Details:
Since the sunvnet and ldmvsw drivers will both use common sunvnet code,
move the functions (and support functions) anticipated to be common code
from sunvnet.c to sunvnet_common.c. Similarly, sunvnet.h was renamed to
sunvnet_common.h. The sunvnet_common.c code will be compiled into the
kernel and act as a library of functions that are linked by either
(or both) drivers when loaded.
Function names for external functions in sunvnet_common.c (to be
called by both the sunvnet and ldmvsw drivers) were tagged with a "_common"
suffix to clearly designate them as common functions.
No functional changes as of yet... just moved code verbatim to the new
sunvnet_common.c/h files.
Makefile/Kconfig support added to build sunvnet_common.c file. The code
is included in the kernel if SUN_LDOMS is defined/selected.
NOTE - per the SubmittingPatches documentation, since the code was just
moved from one file another, the code was NOT checkpatch'd in this commit
to aid in review.
